TOR Tor Weekly News — January 28th, 2015

Welcome to the fourth issue in 2015 of Tor Weekly News, the weekly newsletter that covers what’s happening in the Tor community.

The future of Private Browsing Mode

Mozilla Firefox, on which Tor Browser is based, offers users a “Private Browsing Mode” that aims solely to prevent browsing information from being saved locally. As Georg Koppen pointed out, “The question is now how to treat the other privacy-relevant areas like cross-origin linkability or fingerprinting?”

Georg proposed a “Private Browsing Mode+”, which would integrate the disk-avoidance, anti-tracking, anti-fingerprinting, and location-concealing elements of a privacy-preserving browser in a more logical way.

Miscellaneous news

After a “pretty big overhaul”, Damian Johnson announced that Stem, the Tor controller library, now “lazy-loads” descriptors, resulting in a considerable speed increase when reading network documents. “Note that descriptor validation is now opt-in rather than opt-out, so if you’d prefer validation over performance you’ll now need to include ‘validate = True’.”

Patrick Schleizer wondered how Tor Browser could be made to act more like a “system tor”, and sketched out a possible plan: “What do you think about this proposal in general?”
